Description

Die Erfindung betrifft einen Linearantrieb mit den Merk­ malen des Obergriffes von A1 und A2.The invention relates to a linear drive with the Merk paint the top handle of A1 and A2.

Ein Linearantrieb der gattungsmäßigen Art ist aus dem DE-GM 81 23 668 bekannt. Darin wird ein Linearantrieb be­ schrieben mit einer Spindeleinheit, die über einen Schneckenantrieb von einem Motor angetrieben wird. Auch das US-Patent 41 37 784 zeigt einen Linearantrieb bei dem eine Spindeleinheit über einen Zahnriemen angetrieben wird.A linear drive of the generic type is from the DE-GM 81 23 668 known. In it, a linear drive will be wrote with a spindle unit that over a Worm drive is driven by a motor. US Pat. No. 4,137,784 also shows a linear drive which a spindle unit driven by a toothed belt becomes.

In beiden Schriften ist über die Herstellung der Spindel­ einheit nichts erläutert.In both writings is about the manufacture of the spindle Nothing explained.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Spindeleinheit für den Linearantrieb der im Obergriff ge­ nannten Art zu entwickeln, die sehr einfach, hoch belast­ bar und preisgünstig zu fertigen ist.The present invention has for its object a Spindle unit for the linear drive in the top handle to develop the kind that is very simple, highly stressful is bar and inexpensive to manufacture.

Diese Aufgabe wird durch die kennzeichnenden Merkmale in den beiden einander nebengeordneten Ansprüchen gelöst.This task is characterized by the characteristics in solved the two mutually subordinate claims.

Die Erfindung wird nachstehend an Hand der in den Zeich­ nungen dargestellten Ausführungsbeispiele erläutert.The invention is based on the in the drawing illustrated embodiments explained.

Es zeigen:Show it:

Fig. 1 zeigt einen Schnitt durch eine auf Druck arbei­ tende Spindeleinheit. Fig. 1 shows a section through a pressure-working spindle unit.

Fig. 2 zeigt einen Schnitt durch die Lineareinheit in die eine auf Druck und Zug ausgerüstete Spindelein­ heit eingebaut ist. Fig. 2 shows a section through the linear unit in which a pressure and train equipped Spindelein unit is installed.

Die Spindeleinheit nach Fig. 1 wird bei reiner Druckbelastung verwendet.The spindle unit according to Fig. 1 is used for pure compressive stress.

Dort ist das Schneckenrad (3) so angeformt, daß gleichzeitig ein Befestigungszapfen (4) für die Lagerung (5) angeformt ist. Dies vereinfacht die Herstellung der Spindel, da kein Lagersitz angebracht werden muß. Die Sicherung auf Druck wird durch eine Sacklochbohrung (6) in dem Schneckenrad (3) erreicht.There, the worm wheel ( 3 ) is molded in such a way that a fastening pin ( 4 ) for the bearing ( 5 ) is molded on at the same time. This simplifies the manufacture of the spindle, since no bearing seat has to be attached. The pressure is secured by a blind hole ( 6 ) in the worm wheel ( 3 ).

Die radiale Sicherung wird durch Aufbringen eines Rändels (7) auf den Bereich der überdeckten Spindel erreicht mit einer gleichzeitigen Preßpassung.The radial locking is achieved by applying a knurl ( 7 ) to the area of the covered spindle with a simultaneous press fit.

Ein derartiger Aufbau erlaubt es als Halbzeug zur Fertigung von Spindeleinheiten preisgünstig gerollte Spindelmeterware zu verwenden, und diese durch einfaches Rändeln und Ab­ stechen einpreßfertig herzustellen.Such a structure allows it to be manufactured as a semi-finished product low cost rolled spindle goods from spindle units to use, and this by simply knurling and Ab ready to press-in.

Bei einem Einsatz der Spindeleinheiten auf Zug und Druck (Fig. 2), ist normalerweise eine aufwendige axiale Sicherung durch ein zusätzliches Teil notwendig. Entweder ist eine derart ausgeführte Spindelwelle nicht hoch axial belastbar zum Beispiel bei einer Anwendung von Sicherungsringen, oder ist die Bearbeitung der Spindelwelle durch Aufbringen eines Gewindes mit einer auf gedrehten Mutter sehr kostenintensiv.When the spindle units are used for tension and compression ( Fig. 2), an expensive axial securing by an additional part is normally necessary. Either a spindle shaft designed in this way cannot be subjected to high axial loads, for example when using circlips, or the machining of the spindle shaft by applying a thread with a screwed nut is very cost-intensive.

Die vorliegende Erfindung zeigt eine sehr hoch belastbare axiale Lagerungssicherung.The present invention shows a very resilient axial locking device.

Die Spindelwelle (8) benötigt dazu einen angedrehten Zapfen, auf den das Lagerelement (9) aufgepreßt wird.For this purpose, the spindle shaft ( 8 ) requires a turned-on pin, onto which the bearing element ( 9 ) is pressed.

Danach wird der überstehende Zapfen (10) mittels einer Tau­ melnietmaschine vertaumelt. Das Schneckenrad (11) wird zuvor auf die Spindel (8) gepreßt, wobei die radial auftretenden Momente wieder über einen aufgebrachten Rändel und über eine entsprechende Preßpassung aufgefangen werden.Then the protruding pin ( 10 ) is moored by means of a rope riveting machine. The worm wheel ( 11 ) is previously pressed onto the spindle ( 8 ), the radially occurring moments being absorbed again by means of an applied knurl and a corresponding press fit.
